Currently, when a moderator combines two threads or splits a discussion off of one thread to make a new one, there is no notice to the reader that this was done. This can make some posts be taken out of context, or make some threads difficult to follow.

Sometimes a mod will add a post to say they've combined/split threads, but this doesn't always happen. Can we make this a normal practice? Or maybe add a notice at the top of threads that have been altered?
